I finished this little fellow! (WIP photos here)
It started as a little experiment but I like the result so much I decided to frame it and hopefully someday it will get to be on display in my craft room. Imaginary craft room, that is.

I started with a little scrap of wool felt. I randomly placed some scrap wool roving and lightly needle felted it to the surface. It started to look like a landscape to me so I embroidered the birds and the fence. Then it started to become a garden so I embroidered the edges of the path and needle felted the natural wool to resemble gravel. Then came the french knot (or colonial knot; I don't remember) flower beds, and last came the vegetable patch.

I love it! I feel unreasonably proud of this little thing actually *grins*
I think the combination of techniques and materials worked really well. The needle felted wool has a slightly transparant look, not unlike watercolor. And the whole thing has great texture too.
The scale is a little off though; it's too big to be turned into a brooch and too small to be anything else. So I sewed it into a picture frame to make it easier to display.

I will be experimenting further with this. Maybe next time I will try adding fabric to the mix.
